ECU - CDI ROJO Racing "Dax" Skyteam Zhenhua 50cc (Class A and/or B) for Euro 5 engines with a raised RPM limit of 13,000 and racing mode.
This unit is already activated in racing mode with an RPM limit of 13,000. It must be installed with an aftermarket exhaust to function correctly.
After installation, you need to reset the injection:
1. Secure the ECU to its mount (remove one screw, then a quarter turn).
2. With the ignition off, fully open the throttle and hold it in this position.
3. Turn on the ignition.
4. Wait for the system to detect the ECU (indicator lights will flash).
5. Release the throttle.
6. Turn off the ignition.
7. If everything went well, your machine is ready.
Please note that installing this unit will void your engine warranty.
Reprogramming the ECU via the BT module will reset the RPM limit: Avoid this.
WARNING: Before ordering, please ensure compatibility of this ECU with your machine (EURO 5 - 50cc) as ECUs are NON-RETURNABLE and NON-EXCHANGEABLE under any circumstances.

Doug on 2024-08-25 | The rojo is secured by one screw, is it this screw you remove and do you move the rojo a quarter turn? |
yes exactly |
|
Leevi on 2024-07-24 | Does this work on a 72cc |
Yes |
|
Peetu on 2023-06-14 | will this work on a Zhenhua monkey |
yes = Euro 5 |
|
Ziljo on 2023-06-06 | Does this work on Skyteam Monkey? |
Yes it does |
|
Maeke on 2023-05-09 | is this too much rpm for the 50cc motor? |
The goal of this ECU is to avoid the genuine rpm limit. Of you course your engine must be able to go over the the genuine limit : you must change exhaust, air filter, camshaft, etc... |
|
Make on 2023-05-07 | Do i need to upgrade my camshaft or buy stronger valve springs to be able to run my 50cc @13k rpm or is it possible with the stock parts? |
You will need another camshaft. |
|
Veli-Matti on 2023-04-24 | I buy this part and test it. Skyteam start normally but idle vary betwee 1600-3500. Also little axhaust "shooting". Orginal ecu works normally. Is there something I need to do to get it work right? |
The first thing to do is to reset the box: 1 - Fix the ECU on its support 2 - Switch off the ignition, turn the throttle all the way and stay in this position 3 - Turn on the ignition 4 - Wait until the system detects the ECU (lights flashing) 5 - release the throttle 6 - Turn off the ignition |

Nakki on 2023-04-04 | Does the numbers matter in ecu because in my zhenhua monkey the numbers are ZHF-50N ZH45 SED3Z1 EC28-0068 |
